Application tiled May 2li, 192'1. Serial No. 471,426.

To all whom 'it may concern: j.

Be it knowny that I, WILLIAM RYAN, a citi-- zen ofk the United States,residing at Paso Robles, county of San Luis Obispo, and 5 State ofCalifornia, have invented a new and useful improvement in a DemountableRim,

of which the following is a specification.

My invention relates to improvements in demountable rims for motorvehicles and thc like wherein a continuous rim having a flange thereonoperates in conjunction with a second flange detachably connectedtherewith to form an annular channel to receive a tire.

The primary object of the present invention is to provide a new andimproved demountable rim for motor vehicles and the like.

Another obj ect of the present invention is v to provide a new andimproved device of the character set forth having improved means foreasily and readily connecting and disconnecting a pair of annularflanges to j facilitate removal and placement of a tire or the like.

A further obj ect of the present invention is to provide a new andimproved demountable rim for motor vehicles and of the type set forthwhich may be easily and cheaply consti'ucted, of few parts and having amaximum eliiciency.

I accomplish these several and other objects by means of the improveddevice disclosed in the drawings forming a part of the presentspecification wherein like characters of reference are used to designatesimilar parts throughout the said specification and drawings, and inwhich:

Fig. 1 is a broken transverse sectional view taken through the felloeand rim disclosing the manner in which the same is assembled and held inposition upon amotor vehicle wheel. j v

Fig. 2 is a broken perspective View, partly in section, disclosing therelative position of the parts.

Fig. 3 is an enlarged broken sectional view of the T-shaped slots andthe manner of engaging the lugs; and

Fig. 4 is an elevation ofthe assembled device.

Referring to the drawings the numeral 1 is used to designate acontinuous rim having ring an annular flange 2 formed integral withy oneedge and a plurality of inwardly projecting radial lugs 3 arranged atregular intervals `on the opposite edgethereof.

Asecoiid flange 4, similar t'o the flange 2 on the ring l, is providedwith an inwardly projecting flange 6 having a plurality of regularspaced T-shaped slots 7 therein arranged to match with and engage thelugs 3 `of the rim 1 to form an `annular channel `therewith to receive atire l8, in a manner `hereinafter more fully set forth.

The inner surfaces 9 of the extensions of the T-shaped slots 7 arepreferably beveled or inclined as disclosed in Figs. 2 and 3 of thedrawings whereby rotation of one flange 4 relatively to the flange 2 ofthe rim 1, when the lugs 3 are in said slots 7, will cause said beveledsurfaces 9 to engage said lugs 3 and thereby tightly and rigidly connectsaid flange 4 with the ring 1 to form a rigid and unbroken channel toreceive and effectively retain said tire 'or shoe 8.

The flanges 2 and 4 are also provided with `apertures 11` whereby `asuitable tool, not

shown, may be inserted to facilitate such rotation for connecting anddisconnecting the said flanges.

The connected ring 1 with its flange 2 and connected flange 4 arearranged to be seated upon a suitable felloe band 12mounted upon thewheel 14, said ring 1 being firmly and rigidly held iny such position bythe usual clamps or wedges 16 which are actuated to tighten said ring 1and its attached liange 4 firmly upon said wheel 14.

In removing a tire the flange 4 is rotated relatively to the rim 1 todisengage the lugs 3 from the beveled surfaces 9 of the T-shaped `slots7 and to move said lugs opposite the opening of said slots when theflange 4 may be easily and readily separated from the-said 'Noobstruction now existing, the tire or shoe 8 may be easily removedsidewise from the ring l and a new tire or shoe 8 positioned in placethereof, after which the flange 4. is again replaced and rotated ineither direction to move the lugs 3 into engagement/with eitherextension of the T-shaped slots 7 and into engagement with the beveledor inclined surfaces 9 thereof,`thereby rigidly connecting the `ring 1and channels 2 and 4 to forni risata ened to rigidly secure the ring -1and-flange l in position upon the Wheel 14.

By means of this novel arrangement the flange 4l may be rotated ineither `direction relatively to the ruig lV to engage Vor disen- 'gagethe lugs 3 vvith the beveled surfaces 9 of the T-shaped slots 7, and bythis simpley process a continuous annular channel is formed which willeffectively and properly "hold the tire in position.

It shouldbc `noted then in assemblingv or disasseinbling` this rim thatthere is no tendency to spring` it out of atrue round shape as is thecase` ivithsplit rims Where one end l `must be forced over-the other toremove the shoe.. Consequently a more elficientrim is provided in thepresent instance Which may be easily and readily assembledanddisasgseinbled and which may be cheaply and easily produced.-
